-12n + 7 > -17
-12n > -24
n < 2
When you multiply/divide both sides by a negative value, you switch the inequality sign

-12n+7>-17 <=> leave only n at one side and take all others to the other
-12n>-17-7 <=>
-12n>-24 <=> divide by -12 which is negative so the direcation changes
-12n/-12<-24/-12 <=>
n<2

The reason the greater than sign chages is because whenever you divide or multiply a negative number in this type of equation it switches.

solve just as you would any algebraic equation
(-12n+7) - > (-17)-7
-12n > -24
n < (-24/-12) [remember to change inequality when dividing by a negative number]
n < 2

When you divide it reverses the sign

-12n+7>-17
Subtract 7 from both sides:
-12n>-24
Divide -12 from both sides:
n<2
The sign changed from greater than to less than because both sides were divided by a negative.
